PUMP-ROD-GUIDE BEARING.

To all whom it may concern:

Be it known that I, JULIUS H. RANGE, a citizen of the United States, residin Skidmore, in the county of Bee and tate Texas, have invented certain new and useful Improvements in Pump-Rod-Guide .whereby the latter will be retained in verti-' verse section through Bearings, of which the following is aspecification.

This invention pump rods.

The object of the invention is to provide a roller bearing guide for a pump rod pertains to guides for cal alinement and the wear reduced to a minimum, and further by which the rod will be prevented from unscrewing at the pump.

Finally the object of the invention is to provide ,means of the character described that will be strong, durable, eflicient, and easy of operation, simple and comparativel inexpensive to construct, and also in which the several parts will not be likely to get out of working order.

With the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this s'pecification and illustrated in the accompanymg drawings, wherein: Y

Figure 1. is a vertical section showing the bearing applied to a pump rod, Fig. 2. is a plan view of the same, Fig. 3. is a transoneof the rollersupports,'and Fig. 4. is a detail in perspective of 'one of the members of the roller sup ports, 7 In the drawing the numeral 1, designates .an ordinary pump rod which is square in cross section. At each side. of the rod :1 bearing support 2 is disposed. Each bearmg support comprises two plate members 3 placed one upon-the other. t portion each member is cut inward from its longitudinal edge as shown at 4 in Fig. 4 and the metal between the cuts upset to form a curved housing 5.

he members of each bearing support are placed togetherso that the housings register with their inner contours in the same are of Between the members of each support a bearing roller 6 is disposed and the curvature of the housing is such as to Specification of Letters Patent. Application filed August 30, 1910. Serial No.

, rollers adapted its central Patented Jan. 31, 1911. 579,684.

I retain the roller but at the same time to expose about one-third of its surface.

Each roller has a length substantially equal to the width of one of the sides of the ump rod and is held against longitudinal isplacement by the horizontal portions 7 of the plate members at each end of the housing. The rollers project from the housing a sufiicient distance to engage the sides of the pump rod as is shown in the drawing.

Two of the bearing supports are made longer than the others and have their ends ,fastened on cross beams 8 which latter are fastened on the horizontal timbers 9 of the pum tower. These long supports are dispose so that their rollers 6 will impinge opposite sides of the pump rod, While the short supports are disposed at right angles to the long ones and secured thereto so that their rollers impinge the other two sides of the pump rod.

t is apparent that four rollers are employed, one engaging each side of the pump rod. By this arrangement a guide is formed for the pump rod andthe latter is held against lateral displacement. This construction will reduce wear of the pump rod to a minimum, prevent the pump rod from unscrewing and will be substantially noiseless in its operation.

What I claim is:

1. In a guide bearing for pump rods, a plurality of supports, each support comprising two plate members disposed one on the other and having curved housings, and to impinge the sides of a pump rod, one roller engaging in the housings of each support.

2. In a guide bearing for pump rods, a plurality of supports disposed at right angles to each other and adapted to surround a pump rod, each support comprising two plate members disposed one on the other and having curved housings at their central I'tions, and rollers, a roller being disposed i n the housings of each support and having a portion of its surface projecting from the housings and adapted to engage one of the sides of a pump rod.

3. A pump rod guide bearin support comprising, a pair of elongated p ate members, each member having an upset curved portion at its center, the curved portion of name to this specification in the presence of one member curving 1n a direction opposite two subscribing witnesses. to that of the curved portion of the other member; and a roller secured between the S RANGE curved portions and having less than half Witnesses; of its surface exposed.
